[QUOTE="Larry Mitchell, post: 8911822, member: 694137"] Recently got a 2006 Hyundai Santa Fe as an errand-mobile. It has a JVC KD-R640 single-DIN radio installed by a previous owner (unknown). The wiring was either done by the owner or a quick-&-dirty shop with crimp-on connectors. FM sound is good-for-what-it-is driving around town . That is, until I turn on the running lights / headlights. Noticeable static with the running lights (20%?), overwhelming with the headlights (80%). I've remounted the radio. It was loose in the brackets (& crooked, L to R). It's now snug. Pulled the antenna connector, ensured both ground & signal make good contact, treated it with DeOxit contact enhancer. Actually improved the reception at rest but still static with vehicle lights on. LED conversion on both running lights & headlights but IIRC, was still noisy with incandescent / Halogen. I'm an old IT guy (where I learned about deoxit) but what I know about car audio fits in a thimble. Do I need a filter? Rip out & redo the 16ga wiring done with a head-unit specific kit? Which appears to be done via matching colors on harness to factory wiring. TIA! [/QUOTE]
